The world No. 26, who also defeated Denmark’s former All England champion Tine Baun during the European Team Championships last month, will now play Indonesian qualifier Lindaweni Fanetri in the second round.
The current European junior champion, Marin is fast making a name for herself with her explosive performances.
Her victory over Shao Chieh was also a mark of how far she has progressed in the past seven months, as she had lost to the same player at last year’s World Championships in straight games.
Also through to the second round are top seed Wang Xin and Li Xuerui and Thailand’s Salakjit Ponsana.
Local favourite Juliane Schenk also made it to the next round when she defeated Anastasia Prokopenko 21-4, 21-15. Schenk will now play Eriko Hirose, who beat Fu Mingtian 21-16, 12-21, 23-21.
Meanwhile, Singapore’s Shinta Mulia Sari-Yao Lei (left), stunned top seeds Ha Jung Eun-Kim Min Jung 17-21, 21-14, 21-18, in the women’s doubles.
The Singaporeans had never beaten their rivals in four previous meetings and it looked like they were headed for another defeat when they lost the first game.
They, however, kept calm and took the game to the South Koreans to score a deserved victory. They will now face Germans Sandra Marinello-Birgit Michels in the second round.
Jung Eun still has another chance to win a title as she and Lee Yong Dae reached the second round of the mixed doubles competition after beating China’s Jiaming Tao-Huan Xia 7-21, 24-22, 21-12.
Over in the men’s competition, top seed and defending champion Lin Dan and his compatriot Chen Jin stayed on course for a meeting in the final whey they cruised past their respective opponents on Wednesday.
Chen Jin is chasing a spot in the Olympics and needs to do better than Lin Dan in Germany, England and Switzerland.
